' GaAvLEL DUMP;

Application file'dfNo vember To all whom/2'25 may-concern V Be it knownthat'I, THEODORE A. HAn UNe,

'a citizen of the United States, resid ngat Austin, in thecountyof'Travis and State of Texas, have invented a new and usefulGravel Dump, of which the following is a specification. i

This invention relates to improvements in wvagon construction, and moreparticularly tion, novel means being provided for releasin the sectionsto accomplislrthe purpose of the invention. 7 h With the foregoing andother obe cts 1n view which will appear as the description proceeds, theinvention resides in the c'ombi nation and arrangement of parts and inthe details of constructlon hereinafter descrlbed and claimed, it beingunderstood that changes in the precise embodimentof the invention hereindisclosed, may be made within the scope of what is claimed, withoutdeparting from the spirit of the invention.

Referring to the drawing: v Figure 1, is aplan view of. a wagon bedcoi'istructed in accordance with the invention."

Figure 3 is a sectional .view'taken on line 33- of Figure 1. 7

.Referring to the drawing in, detail, the wagon loody includes sideboards 5 which are connected at their forward ends in any suitable andwell known manner. p The side boards 5 are mounted on the channel irons6 that are bolted or otherwise secured to the bolsters? on which thewagon body is supported, it being understood that the channel irons '6extend theentire length of the body. f

The floor of the wagon bed or bottom includes a plurality of cooperatingsections arran ed in parallel relation with each other as clearly shownby Figure 3 of the draw- Figure 2' is'a side elevational view' there-$3923. Serial No. 673,570. 1

ings'." Each-section is formed with a hinge 8 adapted to embrace thesupporting rod 9 associated therewith, whereby the" sections may swingto theirfo'penor closed positions, at the will of the operator. Asshown, lips 10 are :formed on certain sections of the floor, which lipsoverlie a portion of the adjacent hinged sections to prevent materialfrompassing between the adjacent edges of sections. The supporting rods9 have their ends extended throughthe end members 11 forming a part ofthe wagon body.

The sections vary in length, the outer, or shorter sections beingdesigned to fall to a discharging position; prior to the "moving oftheremaining' sections so that portions of the load may 'bedumpedindependently of the remaining portion thereof. I "Slidably mounted atthe ends of thewagon body are supporting bars 12fthat have their endsdis posed in slots *13 formed adjacent to the ends of the wagon body, sothat theibars may slide throughout the length of the slots and allow thehinged sections forming th bottomto swing downwardly. In order thatthehinged sections will closely engage the supporting bars 12, the endsof the sections extend upwardly at l4=where'. they overlie thesupporting, bars 12.

- Extending through the side boards 5 at a point substantiallyintermediate their ends,

isa rod 15, the length of the rod being greater than the width of thewagon bed to allow the ends" of the rod 15 to extend beyond the sideboards 5 where they support the arms 16, which arms have connection withthe'rods 17 and 181'respectively at points'adjacent to the upperends ofthe arms whereby movement of the arms 16 produces a relative movement ofthe rods 17 and 18.

The rod 17 has pivotal connection with the lever 19 at 20, which ismanuallytoperatedto cause a movement of the rod 17 when it is desired tooperate the supporting bars 12. A dog-21 is provided on the lever 19 andis designed to hold the lever in various positions of adjustment. Thelower end of the lever is pivotallysupported at 22 to pro vide for such'movement of the rod, When the lever 19 is moved.

The rod 18 at theopposite side'o f the bed has pivotal connection withthe bar 23,..at 24;, the lower ends of the bar being tapered andextended-into an opening formed in the supporting bar 12 associatedtherewith,

- movement of the bar 27 is accomplished by the movement of the arms 16.

The supporting bar at the rear end of the wagon body. is actuated bymeans of the arms 30 that are pivotally connected to the wagon body at31 and have reduced end portions 32 extended into openings formed in thesupporting bar associated therewith, the upper ends of the arms 30having pivotal connection with the operating rods 33 that connect withthe arms 16 so thatmovement of the bars at both ends of the wagon bodywill be simultaneous.

From the foregoing it will be obvious that upon movement of the bar 17in the direc tion of the arrow as shown by Figure 2 of the drawing, thesupporting bars at the end .of the wagon body will be moved away fromthe ends of the sections of the bottom of the body to allow the sectionsto swing donnwardly under the weight of the material supported therebyto discharge the load.

,When it is desired to'return the hinged sections of the wagon bodyto'their nori-nal [or supporting positions, the lever'3 l is operated.The lever 34 is pivotally supported at its lower end and has pivotalconnection with the rod 35 that extends dow 'iwardly which in turn haspivotal connection at 36 with the supporting shaft 38 that is hollow andhouses the rod 15 as clearly shown by Figure 3 of the drawings.

Secured to the shaft 38 at a point adjacent to 'one end thereof, is acollar 39 which carries an arm 40 formed with openings to receive thelifting links ll that have connection with sections of the bottomthrough the links 42 so that movement of the arm 40 will'result in arelative movement of the sections associated therewith.

' Collars 43 are also secured to the shaft 38 and are arranged insuitable spaced relation with each other to accommodate the members 44cthathav-e arms 45 formed integral therewitlnwhich arms have connectionwith sections of the bottom through the links 16. Shoulders 47 areformed on the collars 43 which shoulders are engaged by the laterallyextending lugs 48 of the members 44- so that the bottom sections may bemoved simultaneously from their open positions to their closed positionsand at the same time permitting the bottom sections adjacent to one sideof the wagon body may fall downward- 1y to discharge the contents orportion of the load supported thereby, without effecting the remainingsections of the wagon bottom, thereby permitting portions of the load tobe discharged at the will of the operator.

It is therefore obvious thatv by operating the lever 19, to move thesupporting bars slightly to disengage the shorter sections of the wagonbottom. the shorter sections will be permitted to drop partiallyrotating the shaft 38 and moving the shoulders 47cm of engagement withthe members 44, while a further movement of the lever 19 will permit theadjacentsections of the bottom to swing downwardly while a still furthermovement of the lever 19 to mov the supporting bars out of engagementwith the remainingbottom sections will permit the last mentionedsections to drop. 7 When-it is desired to return the sections to theirnormal or supporting positions. the lever 34 is operated moving theshaft 38, whereupon the shoulders 47 of the collars 4l3'contacting withthe laterally extending lugs of the members let will pick up the members4% and move them to theirnorinal positions. When the shaft 38 is rotatedby a. movement of the lever 34, due to the fact that members 44: haveconnection with the bottom sections it is obvious that the bottomsections are moved upwardly or to their active positions. 7

It mightbe further stated that the movement of the rod 35 is restrictedby the coiled spring 49 which has connection with the rod 35 to the link50, the opposite end of the coiled spring being anchored at 61 to thebody portion.

At the ends of the body portion are eye plates 32 through which hoistinghooks may be positioned when it is desired to lift the wagon body fromthe running'gear supporting the same. 7

I claimr In a dumping wagon "body, a sectional bot tom, means forpermitting the -sections to be moved to their discharging positionsindependently of each other, a shaft'extending transversely of the body,collars loosely mounted on the shaft and having shoulders, collarssecured to the shaft adjacent to the first mentioned collars and havingshoulders adapted to cooperate with the first mentioned shoulders tomove the first mentioned collars with the shaft when the shaft isrotated, and means connecting the collars to the floor sections disposedthereunder.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signatur in the presence of twowitnesses.

THEODORE AUGUST HARTUNG.
